论文摘要
我们提出了一种非线性成像方案，该方案具有未检测到的光子，该方案通过以一个波长的近场信息传输近场信息，以克服衍射极限，以与通过自发光子对生成产生的不同波长的相关光子的远场信息。同时，该方案允许检索具有零背景的高对比度图像，这使其成为具有细分光谱分辨率的充满挑战的光谱范围内的小物体的高度敏感方案。
We propose a nonlinear imaging scheme with undetected photons that overcomes the diffraction limit by transferring near-field information at one wavelength to far-field information of a correlated photon with a different wavelength generated through spontaneous photon-pair generation. At the same time, this scheme allows for retrieval of high-contrast images with zero background, making it a highly sensitive scheme for imaging of small objects at challenging spectral ranges with subdiffraction resolutions.
